I used to do that (setting $sp) in an ancient testcase whose purpose
was to break the callstack. It turned out that breaking the callstack
was too platform specific, so I gave up on using this.

I am guessing that some people might try setting $sp for various
purposes (maybe debugging a problem with code that misaligns SP
for instance), and a screwup might lead to this situation too...
